From the Guidelines

Hydroxychloroquine is not recommended for the treatment of psoriatic arthritis, as stated in the 2009 study published in the Annals of the Rheumatic Diseases 1. Instead, treatment recommendations for peripheral arthritis include non-steroidal anti-inflammatory drugs (NSAIDs), intra-articular glucocorticoid injections, disease-modifying antirheumatic drugs (DMARDs), and TNF inhibitors. The European League Against Rheumatism (EULAR) also recommends the use of DMARDs, such as methotrexate, sulfasalazine, and leflunomide, for the treatment of active psoriatic arthritis 1. More recently, the 2018 American College of Rheumatology/National Psoriasis Foundation guideline for the treatment of psoriatic arthritis emphasizes the importance of early identification and treatment of PsA to improve long-term outcomes, and recommends the use of pharmacologic therapies such as NSAIDs, DMARDs, and biologic agents 1. Key points to consider in the treatment of psoriatic arthritis include:

  • The primary goal of treatment is to maximize long-term health-related quality of life, through control of symptoms, prevention of structural damage, and normalization of function and social participation.
  • Treatment should be adjusted regularly based on disease activity and patient response.
  • Patients with active disease should be considered for treatment with DMARDs or biologic agents.
  • Regular monitoring and follow-up are essential to ensure optimal treatment outcomes. In terms of specific treatment options, the 2018 guideline recommends the use of:
  • NSAIDs for symptomatic relief
  • DMARDs, such as methotrexate, sulfasalazine, and leflunomide, for disease modification
  • Biologic agents, such as TNF inhibitors, for patients with active disease who have not responded to DMARDs. Overall, the treatment of psoriatic arthritis should be individualized based on patient-specific factors, such as disease severity, comorbidities, and treatment preferences.

From the Research

Time Frame for Hydroxychloroquine to Show Results in Psoriatic Arthritis

  • There is limited information available on the specific time frame for hydroxychloroquine to show results in psoriatic arthritis 2.
  • The provided studies primarily focus on the use of methotrexate in the treatment of psoriatic arthritis, with no direct mention of the time frame for hydroxychloroquine to show results 3, 4, 5.
  • One study from 1982 discusses the use of hydroxychloroquine in psoriatic arthropathy, but it does not provide information on the time frame for the drug to show results 2.
  • A more recent study from 2023 discusses the management of psoriatic arthritis in different clinical scenarios, but it does not mention hydroxychloroquine specifically 6.

Available Information on Hydroxychloroquine

  • The 1982 study found that hydroxychloroquine exacerbated psoriatic skin lesions in a patient with psoriatic arthropathy 2.
  • There is no other information available in the provided studies on the use of hydroxychloroquine in psoriatic arthritis, including the time frame for the drug to show results.

Conclusion on Available Evidence

  • Based on the provided studies, there is no direct evidence available to answer the question of how long it takes for hydroxychloroquine to show results in psoriatic arthritis.
  • The available studies primarily focus on the use of methotrexate in the treatment of psoriatic arthritis, with limited information on hydroxychloroquine.
